Dualok Interconnect System

A harsh environment interconnect system with superior electrical performance

Dualok is an enhanced anti-decoupling mechanism that can be used on virtually any cylindrical plug connector and backshell.

The Dualok Interconnect System greatly improves electrical performance in harsh environments while providing a size and weight savings when compared to standard connectors in the same class.

Dualok technology is applied to the plug connector and backshell only and will mate with standard receptacles.

DUALOK TECHNOLOGY BENEFITS:

SUPERIOR ELECTRICAL PERFORMANCE

Better shell-to-shell conductivity

Assures EMI protection at high frequencies

Minimized contact fretting

SUPERIOR HARSH ENVIRONMENT PERFORMANCE

Extreme vibration capabilities at wide temperature range

Enhanced corrosion protection with composite materials

Reduces relative motion

SIZE AND WEIGHT SAVINGS

Lightweight, hybrid composite/metal design

Smaller footprint/space savings

Alternate to Cadmium, RoHS-Compliant Platings

DURMALONTM - AMPHENOL'S ANSWER TO EU RoHS/ELV/CADMIUM FREE RESTRICTIONSCommercial, industrial & military markets are rapidly moving away from restricted materials such as Cadmium (Cd) & Hexavalent Chromium (Cr(VI)). Both of these restricted materials are toxic and known carcinogens. Amphenol is offering an alternative finish that complies with all customer requirements tied to these specifications. MIL-DTL-38999, Rev L has established new service classes as alternative finishes addressing these requirements for Cadmium replacement. Amphenol is using this and European Union Directive 2002/95/EC RoHS (Regulation of Hazardous Substances) as a guide to qualification for all domestic, global, commercial, industrial, & military specifications requiring the reduction or elimination of these restricted materials. Amphenol has qualified Durmalon, with internal part number coding “DT” finish, which meets or exceeds the 38999 designated class “T” finish, Nickel Fluorocarbon Polymer. Durmalon is also EU RoHS compliant and is Cadmium free, Lead free , and Hexavalent Chromium free. Cadmium has been applied to numerous components of land, sea and air weapon systems and NASA systems for many years as it provides sacrificial corrosion protection and excellent lubricity for threaded applications.

THE DEFENSE LOGISTICS AGENCY (DLA) HAS ADDED THE FOLLOWING CADMIUM ALTERNATIVE FINISHES TO MIL-DTL-38999, REV L (AND OTHER CONNECTOR SPECS):

Interest for non-hazardous alternative finishes are gaining momentum & many customers are currently using Durmalon for a broad number of applications. Durmalon combines the unique lubrication and anti-wetting properties of PTFE with corrosion resistance, high conductivity, and EU RoHS compliance in a non-reflective finish. Durmalon can be used as a drop-in replacement for Cadmium and is compatible with other platings.

Black Zinc Nickel joins DurmalonTM as Amphenol’s Second RoHS Compliant Plating Alternative to Cadmium Amphenol is now offering a new RoHS compliant alternative to Cadmium. Black Zinc Nickel is a non-reflective and conductive black finish approved for 500 hrs salt spray making it an excellent choice for harsh environments. Black Zinc Nickel has been qualified by the DLA, with internal part number coding “DZ” finish, which meets or exceeds the 38999 designated class “Z” finish. Black Zinc Nickel is compatible with other platings and available on a wide variety of connectors and accessories including all MIL-DTL-38999 Series III connectors.

Interest for non-hazardous alternative finishes are gaining momentum & many customers are currently using Black Zinc Nickel for a broad number of applications. Black Zinc Nickel is typically used on applications for commercial aerospace and military defense, who are now moving away from toxic Cadmium to more environmentally friendly options.

Matrix MIL-DTL-26482 (2)

Amphenol broadens their Miniature Circular Family of Connectors with the addition of the Matrix® Product line of MIL-DTL-26482 series II connectors. The Matrix MIL-DTL-26482 series II provides a bayonet coupling connector with crimp rear insertable, rear releasable contacts.

FEATURES AND BENEFITS

Medium size, environmentally resistant connector

Recommended operating voltage to 1,000 VAC (RMS) at sea level

Quick positive coupling assured by 3 point bayonet coupling system

Visual confirmation of complete coupling

Eliminates mismating by the use of five key/keyway design

Insertion and removal of contacts from the rear of the connector assures no damage to the front that might affect the sealing characteristics

Grommets are constructed of tear-resistant elastomer and experience no degradation when exposed to a broad range of fluids

Sealing over a range of wire diameters is assured by a triple webbed grommet at the rear of the connector

Closed entry socket side of the insert is designed with a lead-in chamfer and a hard face that will accept a pin contact bent within pre-established limits

Elastomer interfacial seal on the pin side has raised barriers around each pin which displace into the socket chamfer when mated, providing a positive moisture seal
